first embodiment
[0028]FIG. 3 is a schematic configuration view showing a magnet fracture apparatus representing a field-pole magnet manufacturing apparatus according to a first embodiment. FIG. 4 is an enlarged view showing major components of the magnet fracture apparatus. A magnet fracture apparatus 40 for a field-pole magnet (hereinafter simply referred to as “magnet”) 30 fractures the magnet 30 into a plurality of magnet pieces 31. The magnet fracture apparatus 40 includes a tool set composed of a lower tool 50 and an upper tool 60. The lower tool 50 supports and guides the magnet 30. After the position of the magnet 30 has been set, the upper tool 60 fractures the magnet 30 by pressing a blade 61 against the magnet 30. The magnet fracture apparatus 40 also includes a positioning device 70 and a suction device 80. The positioning device 70 sequentially moves the magnet 30 supported by the lower tool 50 so as to set the magnet 30 at a fracture position. The suction device 80 suctions and dischar...
second embodiment
[0057]FIG. 8 is a schematic configuration view showing a magnet fracture apparatus representing a field-pole magnet manufacturing apparatus according to a second embodiment. The present embodiment is achieved by adding, to the configuration of the first embodiment, a configuration for blowing the air onto the upper surfaces of a pair of projections located at the front side and the rear side of a through-hole in a lower tool. It should be noted that the components that are the same as the components of the manufacturing apparatus according to the first embodiment are given the same reference signs thereas, and a description thereof is omitted or simplified below.
[0058]According to the magnet fracture apparatus according to the second embodiment shown in FIG. 8, air blow openings 55 penetrate in the up-down direction through the pair of projections 51 located at the front side and the rear side of a through-hole 52 in a lower tool 50 supporting a magnet 30. The air is supplied to the...
third embodiment
[0063]FIG. 9 is a schematic configuration view showing a magnet fracture apparatus representing a field-pole magnet manufacturing apparatus according to a third embodiment. The field-pole magnet manufacturing apparatus according to the third embodiment differs from the field-pole magnet manufacturing apparatus according to the first embodiment in a configuration of a suction device 80. More specifically, in the present embodiment, the suction device 80 does not include an elevator member, and is fixed to a base 88. In this configuration also, the suction device 80 can suction crush powder produced at the time of fracturing the magnet 30 and discharge the crush powder to the outside of a tool set.
